    • A system and method to enable a wireless device having multiple radios to obtain information about wireless networks without each radio having to independently scan for all available networks. The wireless device downloads information from a remote information server, such that the information is later accessible locally. The local information server may be updated independently according to the preferences of the user. The system enables any of the radios to obtain access information without having to perform time- and power-consuming scanning operations, where the access information is sufficient for the radio to make contact with the wireless network, irrespective of whether the radio is tailored to support that network. The system may include wireless neighborhood map(s) of one or more geographic regions. The wireless device is able to ascertain the wireless network landscape of a region without having to actually reside in the geographic region.
    • 一种使具有多个无线电的无线设备能够获得有关无线网络的信息的系统和方法,而无需每个无线电单元必须独立扫描所有可用的网络。 无线设备从远程信息服务器下载信息,使得该信息稍后在本地可访问。 可以根据用户的偏好独立地更新本地信息服务器。 该系统使得无线电设备能够获得访问信息,而不必执行耗时和耗时的扫描操作,其中访问信息足以使无线电与无线网络接触,而不管无线电是否被定制为支持 那个网络。 系统可以包括一个或多个地理区域的无线邻域图。 无线设备能够确定区域的无线网络景观,而不必实际居住在地理区域中。

    • A system and method to enable a transparent, outboard, proxy secure channel between two endpoints on a Local Area Network (LAN) using front-end network encryption devices are provided. A secure channel provides an encrypted, authenticated communications pathway that protects an otherwise insecure communications network against threats including passive eavesdropping, active modification and insertion, and impersonation. One version provides a fully transparent secure channel between two endpoints which may be unaware of the data protection being applied. An alternate version enables single-ended communications protection between an endpoint transparently protected by a front-end network encryption device and a remote endpoint having compatible, interoperable encryption software. In a single-ended application, the remote endpoint may be unaware that (1.) the other endpoint is not performing the encryption nor that (2.) a front-end network encryption device is performing the encryption on its behalf.
    • 提供了一种使用前端网络加密设备在局域网(LAN)上启用两个端点之间透明的外部代理安全通道的系统和方法。 安全通道提供加密的经认证的通信路径,其保护否则不安全的通信网络免受包括被动窃听,主动修改和插入以及冒充的威胁。 一个版本在两个端点之间提供完全透明的安全通道,可能不知道正在应用的数据保护。 替代版本允许在由前端网络加密设备透明保护的端点与具有兼容的可互操作加密软件的远程端点之间进行单端通信保护。 在单端应用程序中,远程端点可能不知道(1)另一个端点不执行加密,或者(2)前端网络加密设备代表其进行加密。

    • A building evacuation system in which at least one vertical evacuation chute is provided for each floor of a building to be evacuated. A plurality of collapsible buckets are stored on each floor and, after loading, are slid along horizontal rails to the vertical chute where they engage a plurality of vertical guide tracks. The guide tracks are provided with tapered brake pads so as to provide progressively increasing braking force on the falling buckets. A sloping slide is provided adjacent a lower open end of the chute to slidably transfer the bucket and evacuee to the ground.
    • 一种建筑物撤离系统,其中为要排空的建筑物的每个楼层提供至少一个垂直疏散滑槽。 多个可折叠的桶被存储在每个楼层上,并且在装载之后,沿着水平轨道滑动到垂直滑道,在那里它们接合多个垂直导轨。 引导轨道设有锥形刹车片,以便在落下的铲斗上提供逐渐增加的制动力。 在滑槽的下开口端附近设置倾斜的滑动件,以将铲斗和撤离器可滑动地传送到地面。
